Abstract
A system and method for high-speed alignment and inspection of components, such as BGA devices, having non-uniform features is provided. During training time of a machine vision system, a small subset of alignment significant blobs along with a quantum of geometric analysis for picking granularity is determined. Also, during training time, balls may be associated with groups, each of which may have its own set of parameters for inspection.
